To all whom it 11mg concern:

Be it known that 1, WILLIAM MICHAEL, a citizen of theUnited States,residingat Marion, in the county of Grant, State of Indiana, haveinvented certain new and useful Improvements in Scaffold-Brackets; and Ido hereby declare thefollowing to be a full, clear, and exactdescription of the invention, such as" will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to brackets such as are employed upon ladders forsupporting scafiolding; and it has for its object to provide aconstruction which may be easily and quickly attached to and detachedfrom the ladders, which will be cheap and durable,

and which may be adjusted to correspond to different inclinations of aladder. 1

Other objects and advantages of the invention will be understood fromthe following description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in both views, Figure1 is a perspective view showing a bracket attached to a ladder andsupporting,- one end of the scafiold-plauln Fig. 2 is a'perspective viewof the bracket detached from the ladder. Referring now to the drawings,there is shown a bracket comprising a member 5, which is designed toreceive directly a scaffold-plank 6 and which member has at one end across-piece 7, having a longitudinal channel 8 in its under face inwhich is received a rung'9 of a ladder in the use ofthe bracket, themember 5 at such time being disposed in horizontal position, asillustrated in Fig. 1 of the drawings. At the opposite end of the member5 from the cross-piece 7 is formed alongitndinal slot 10 and resultantspaced members 11 and 12, through which is engaged a transverse pin 13,which is spaced outwardly, from the inner end of the slot to receivebehind it the narrowed upper end or tongue 14 ofa brace 15. Theformationiof the narrowed tongue results in shoulders 16, upon which thespaced members 11 and 12 Serial No. 162,556. (No model.)

a plate which is pivotally mounted in the longitudinal slot 19 in thelower end 0t the brace, said foot being limited in its pivotal movementby the upper end of the slot in 4 which it is pivoted. The foot projectsat 0pposite sides of the brace, and in the under face of its projectingend portions are formed notches 20, and in the arrangement of the braceits lower end is disposed beyond the rung of the ladder, so that saidrung is engaged with the notch of the foot at the outer side of thebrace. With the pivotal arrangement of the foot and its projection atboth sides of the brace the supporting member 5 of the bracket may bearranged to project at either side of the brace, and the foot may beswung into proper position to correctly support the brace and engage therung.

It will be noted that the spaced members at the end of the supportingmember 5 have a plurality of perforations which aline in pairs and whichpairs of perforations are designed to interchangeably receive the pin13, so that the pin, in connection with the base of the slot, will holdthe brace andlsupport- 1 transverse pin and the base of the slot andhaving a longitudinal slot in its opposite end, and a foot pivoted inthe longitudinal slot of the brace and projecting with its ends atopposite sides of the latter, said foot having In testimony whereof Iaffix my signature in presence of two Witnesses.
